What the questions are drawn from
14 CFR Part 5 is titled Safety Management Systems and is organized into safety policy, safety risk management, safety assurance and safety promotion, with a further subpart on documentation and records. The 27 questions follow that structure, and each one names the section it comes from.
Scoring is two points for a full yes, one for partly, none for no, so 54 is the maximum. The score is a description of your own answers. Where you actually stand with a regulator is a conversation with an auditor, not a number a website can give you.
